are produced using Fairchild s proprietary, high cell density,
DMOS technology. These products have been designed to
minimize on-state resistance while provide rugged, reliable,
and fast switching performance. They can be used in most
applications requiring up to 400mA DC and can deliver
pulsed currents up to 2A. These products are particularly
suited for low voltage, low current applications such as small
servo motor control, power MOSFET gate drivers, and other
switching applications.

Description: This paper presents an application of rotor field
oriented control (RFOC) to a five-phase induction motor with
the combined fundamental and third harmonic currents. Based
on the motor model developed in a new d,q, n reference
frame, the complete theory and modeling of rotor field oriented
control of the five-phase induction motor are established.
Specifically, investigation is made to improve power density and
output torque of the five-phase induction motor by injecting
third harmonic of currents. By the proper dynamical
adjustment and steady state compensation, the rotor field
oriented control of the five-phase induction motor not only
achieves a high drive performance, but also controls the
fundamental and third harmonic flux and torque to generate the
desired nearly rectangular air-gap flux. Both simulation and
experimental results further verify the theoretical analysis and
demonstrate the feasibility and practical value of the proposed
five-phase induction motor drive.-This paper presents an application of rotor field
